Daniel0 Posted November 15, 2009 Share Posted November 15, 2009 You can use at on Linux. It's essentially a one-time cronjob. Quote Link to comment Share on other sites More sharing options...
mrMarcus Posted November 15, 2009 Share Posted November 15, 2009 a very simple way would be using AJAX (jQuery/MooTools) .. with AJAX, you can set a timer to execute a file of your choice asynchronously on the server. that file could be to delete a file, or whatever you like. it could work like such: person reaches link/page; countdown timer commences; 0 is reached, AJAX runs unlink.php?file=file_to_be_removed.txt; i have no idea how your system is setup, but anytime you are dealing with deleting files, etc., security is crucial.

mrMarcus Posted November 15, 2009 Share Posted November 15, 2009 i know you can write a CRON job with PHP. i've never played around with it, but you could use it to write a cron to be execute 1 minute from that point in time, and have the cron run you deletion script/file. need to be able to use exec() on your server.

xcoderx Posted November 16, 2009 Author Share Posted November 16, 2009 something like this would work? $content = 'messages/'.$file.'.txt' -mmin -60 -exec rm -f {} \; unlink($content); Quote Link to comment Share on other sites More sharing options...

Daniel0 Posted November 16, 2009 Share Posted November 16, 2009 If you're going to use the command line, why not just use at like I already suggested? Quote Link to comment Share on other sites More sharing options...
